DC Electronic Load

Model 8540

The 8540 DC electronic load is a very compact, economically priced
instrument that is at home on both the bench and the production floor.

Though this is a DC load in a small package, it can reliably test a 5 volt
power supply to 30 amps and do it continuously.

The 8540 DC electronic load can operate in CC, CV or CR mode while
voltage/current or resistance/power values are measured and displayed in real
time, making it well suited to test a variety of DC power sources.

The 8540’s performance is comparable to most full size bench DC loads, yet
it does the job at half the price and takes up half the space on your bench.

Features & Benefits

■ Operates between 0-60 VDC, 1 mA-30 A (150 W maximum)

■ Easy operation

■ Bright, easy-to-read display

■ Very compact and light weight

■ Two current ranges: 3 A (1 mA resolution) and 30 A (10 mA

resolution)

■ Constant current (CC), constant resistance (CR) and constant voltage

(CV) operation

■ Over-current and over-voltage protection

■ Short mode to simulate shorts

■ Save up to 400 instrument settings
